This instructables is slightly too late for Christmas, but it's so damn cool that you'll want to start your project now. Basically, you take a Tesla Pump (yeah, that Tesla), and use it to swirl liquids around in a pipe.

It's no easy project, since if you want to do it the way shown, you'll have to conjure up a Subaru blower fan motor, some neodymium magnets and a big-ass tube to put the whole contraption in. I'll let Instructables show you the rest. [Instructables]
